后台代码：
public partial class Car : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bindDatalist();
}
}
private void bindDatalist()
{
//获取传入购物车，绑定数据
this.DataList1.DataSource = Session["Cartit"];
int count = 0;
foreach (CartItem item in (ICollection)Session["cartit"])
{
count++;
}
this.count.Text = count.ToString();
this.DataList1.DataBind();
}
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (("Edit"))
{
this.DataList1.EditItemIndex = e.Item.ItemIndex;
bindDatalist();
}
//else if (("Update"))
//{
// Label la1 =(Label) e.Item.FindControl("itemid");
// int itemid=int.Parse(la1.Text);
// foreach (CartItem item in (ICollection)Session["cartit"])
// {
// if (item.Id==itemid)
// {
// item.Quantity++;
// }
// }
// DataList1.EditItemIndex = -1;
// bindDatalist();
//}
}
protected void DataList1_CancelCommand(object source, DataListCommandEventArgs e)
{
DataList1.EditItemIndex = -1;
bindDatalist();
}
protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
{
Label la1 = (Label)e.Item.FindControl("itemid");
int itemid = int.Parse(la1.Text);
foreach (CartItem item in (ICollection)Session["cartit"])
{
if (item.Id == itemid)
{
item.Quantity++;
}
}
Page.RegisterStartupScript("msg", "<script>alert('更新成功！')</script>");
DataList1.EditItemIndex = -1;
bindDatalist();
}
这是一个购物车模块
进入编辑状态之后，输入新的商品熟练，点击更新按钮，从新绑定，但是，既不执行ItemCommand中关于update 的代码，也不执行Update事件，请问到底为什么，谢谢，这是我全部的分
